36117127, Ji. merlfl'l MQTWL Mag ATTORNEY Patented May 2, 1933 UNITED STATES PATENT OFFICE Y RALPH K. MERRILL, OF GRAND RAPIDS, MICHIGAN, ASSIGNOR TO AMERICAN SEATING COMPANY, OF GRAND RAPIDS, MICHIGAN, A CORPORATION NEW JERSEY HINGE non MoUNTTNGjDEsK Tor Lrns Application ledAugust 9, 1930. Serial No. 474,237.

The present invention relates to hinges for mounting the lids of desk tops and the like; and its object is to provide such a mounting hinge which may be securely and rigidly 5 fastened to said parts; and further, to provide in such a hinge improved means for preventing the warping of the lid; and further, to provide in such a hinge improved means for mounting the same in adjustable relation to the lid.

These and any other and more specic objects hereinafter appearing are attained by, and the invention finds preferable embodiment in, the device particularly described in the body of this specification and illustrated by the accompanying drawing forming a part hereof, in which Figure 1 is a bottom plan view of a swingable lid and a portion of a desk top on which the lid is mounted;

Figure 2 is a vertical sectional view thereof taken on line 2-2 of Figure 1;

Figure 3 is a vertical sectional view of certain parts of the same taken on line 3-3 of Figure 1; and

Figure 4 is a vertical sectional view of certain parts taken on line 4-4 of Figure 1.

In the drawing, a desk structure is shown having a box top forming an upwardly open chamber 1 and a Xed horizontal wall 2 closing the rear portion of the chamber. On this wall 2 is mounted a swingable lid 3 adapted to be raised and lowered to open and to completely close the chamber. This lid is mounted on said wall 2 by a hinge having two leaves 4, 5, connected by a pintle 6, the leaf 4 being secured to wall 2 as by screws 7.

The lid 3 has a groove 8 in its under side, extending in its transverse direction and having overhanging sides 9, 9 which, as particularly shown in Figure 3, are inclined, and diverge inwardly or toward the bottom 10 of the groove. The hinges leaf designated generally 5 is elongated in the direction of the groove and is thrust endwise thereinto.

This elongated leaf has a middle or web portion 11 and springable iiange portions or sides 12, 12 which extend laterally inwardly from said middle portion, divergingly from eachother and parallelly' with the inclined` sides 9,` 9 of the groove. To seat this elongated leaf 5 in tight contact with said sides of the groove, afiller strip 13 having inclined edges 14 is driven into the groove between and. in contact with the bottom 10 of the groove andthe inclined sides 12, 12 of said leaf, so as to bindor clamp said sides of the elongated leaf between the filler strip and the inclined sides 9, 9 of the groove. It will be seen that the said elongated leaf is thus not only rigidly secured to the lid 3, but that it also prevents the same from warping and like deformation. l Y y This elongated leaf 5 has an outer end portion 15; which extends outside the groove and contacts theV under surface of the lid and has a longitudinally extending slot 16 through which a screw 17 is passed into the lid, the lid being thus adjustable forwardlyrearwardly on said leaf. In the chamber 1 of the desk top a friction plate 18 ismounted, on which frictionally bears (inthe opening and closing movement of the lid) a friction plate 19y formed integrally with the hinges elongated leaf 5 Vby bending over a portion thereof.

As indicated in the drawing, the leaf designated generally 5 is desirably formed of two metal plates, one of them, 20, having the bearings for the pintle 6 and the other, 21, being the part seated in the groove, these plates 20, 21 being united by rivet portions 22 and spot welding indicated at 23. The lid 3 is thus mounted on the desk top by a pair of these hinges adjacent the ends respectively of the structure.-

- The invention being intended to be pointed out in the claims, is not to be limited toor by details of construction of the particular embodiment thereof illustrated by the drawing or hereinbefore described,

- I claim:

' 1. In combination with a desk top and a swingable lid therefor having in its under side a transversely-extending groove with overhanging sides, means for mount-ing the lid onthe desk top comprising: a hinge having a leaf securedto the desk top and an elongated leaf seated in the groove in coninwardly diverging sides, means for mount# tacting the under surface of the lid; and means for securing said leaf to the lid in longitudinally adjusted position relative thereto.

In testimony whereof I have hereunto set 0 my hand at Grand Rapids, Michigan, this 6th 7 day of August, 1980.
